BACKGROUND

The present disclosure relates to lighting a work area, and moreparticularly, to a method and apparatus for attaching a light to ahead-worn device.

Some work environments, such as, for example, a welding environment, canbe dark and in some cases confined. Accordingly, in such cases lightingcan be difficult to focus on the specific spot that is in need ofillumination for the operator to clearly view through, for example,their welding helmet. Due to the confined spaces and the need tomaneuver around work pieces, a light attachment needs to be solidlymounted to the protective device so it does not become dislodged or outof adjustment if bumped against items within the weld environment.

Limitations and disadvantages of conventional systems for lighting awork area will become apparent to one of skill in the art throughcomparison of such approaches with some aspects of the present methodand system set forth in the remainder of this disclosure with referenceto the drawings.

SUMMARY

Methods and systems are provided for a method and apparatus for lightinga work area, substantially as illustrated by and described in connectionwith at least one of the figures, as set forth more completely in theclaims.

FIG. 1A is a drawing of an example helmet where the protective visor isnot in use, in accordance with an embodiment of the disclosure.Referring to FIG. 1A, there is shown a head-worn device 100 being wornby a user. The head-worn device 100 comprises a support unit 102 forwearing the head-worn device 100 on the head of the user, a protectiveshield 104 that is rotated up, an anchor (pivot) point 106 about whichthe protective shield 104 rotates up or down, a light bracket arm 108,and a light source 110. The light source 110 can be attached to thelight bracket arm 108 via, for example, a light source holder 112. Thelight source holder 112 may be a separate piece from the light bracketarm 108 in some embodiments, and a single unit piece in otherembodiments. The light source holder 112 may be any type of device thatcan hold a light source 110 such as, for example, a clip. When the lightsource 110 is turned on, the light beam 111 can shine on the work area113.

The head-worn device 100 may be, for example, a welding helmet and theprotective shield 104 may protect the user from the light of the weldingtorch as well as splattering material from the work area 113. Variousembodiments of the disclosure have the light bracket arm 108 such thatthe light bracket arm 108 does not move substantially when theprotective shield 104 is rotated up or down. This will be described inmore detail below with FIGS. 2-6.

While in some cases, having additional lighting may still be helpfuleven when the protective shield 104 is rotated up, in other cases whenthe additional light is not needed, the light source 110 may be turnedoff to conserve power when the protective shield 104 is rotated up.Accordingly, in some embodiments the light source 110 can be providedwith an on/off switch (not shown). Various embodiments may also providefor turning the light source 110 on/off depending on the position of theprotective shield 104. For example, if the protective shield 104 isrotated up, the light source 110 may be turned off automatically, and ifthe protective shield 104 is rotated down, the light source 110 may beturned on automatically. The light source 110 may also be turned on oroff automatically depending on the ambient light sensed by a sensor (notshown) on the head-worn device 100.

A user interface (not shown) may facilitate controlling the light source110. The user interface may comprise an on/off switch, a switch to allowautomatically turning on and off the light source 110, whether bymovement of the protective shield 104 or by a light sensor (not shown).The user interface may control the light source 110 via a wirelessconnection or a wired connection. The light sensor may communicate withthe user interface via a wireless connection or a wired connection. Thelight sensor may be placed at any convenient place on the interior orexterior of the head-worn device 100, attached or hanging on the body ofthe user (on clothing, hanging around the neck, etc.), or placed in anearby location.

The light source 110 shown is a basic representation of a light thatcould be used. Given current battery and LED light technology, lightscan be much more efficient, but most welders need lighting throughouttheir shift, in many cases 8-10 hours. Due to this longevityrequirement, some embodiments may provide a larger battery to eliminatethe need to change batteries through the day. In various embodiments,the light source 110 could have replaceable batteries and/or an internalrechargeable battery.

Where the light does not need to be on for an extended period of time,but weight is an issue, the light source 110 may use smaller “coin”batteries. Still other embodiments may require very bright lights for along period of time. In such cases, a battery pack (not shown) may beconnected to the light source 110, where the battery pack may beattached to a different portion of the head-worn device 100, to awearable item such as a work belt of the user, or worn on the body, forexample, by strapping the battery on to the user's back. Still otherembodiments may use a light source 110 that can receive powerwirelessly. Accordingly, various embodiments of the disclosure are notlimited to a specific type of light or power for the light.

FIG. 1B is a drawing of an example helmet where the protective visor isin use, in accordance with an embodiment of the disclosure. Referring toFIG. 1B, there is shown the head-worn device 100 being worn by a usersimilarly as in FIG. 1A except that the protective shield 104 is rotateddown to protect the user. Various embodiments of the disclosure willallow the light bracket arm 108, and hence the light source 110, toremain substantially stationary even when the protective shield 104 isrotated up or down.

FIG. 2 is a drawing of an example device for attaching a light to ahelmet, in accordance with an embodiment of the disclosure. Referring toFIG. 2, there is shown the head-worn device 200 comprising the supportunit 202 that may be similar to the support unit 102. A light mountingassembly 250 is attached at the anchor (pivot) point 206, which issimilar to the anchor (pivot) point 106 about which the protectiveshield 104 rotates. The light mounting assembly 250 can comprise aheadband depth positioning slide 252 that is locked to the support unit202. The rotating coupler 254 is rotatably attached to the headbanddepth positioning slide 252.

The rotating coupler 254 rotates with a protective shield such as, forexample, the protective shield 104. Next to the rotating coupler 254 isthe headgear washer 256, a headgear o-ring 258, and a pivot tensioningknob 260. The rotating coupler 254, the headgear washer 256, theheadgear o-ring 258, and the pivot tensioning knob 260 can be mountedon, for example, an axle 252 a protruding from the headband depthpositioning slide 252. While the rotating coupler 254 can rotate aboutthe axle 252 a, the headgear washer 256, the headgear o-ring 258, andthe pivot tensioning knob 260 do not rotate about the axle 252 a oncethose components are tightened in place by the pivot tensioning knob260. The pivot tensioning knob 260 may also be referred to as aconstant-angle portion since it should not rotate when the protectiveshield 104 is rotated up or down. Other parts that also do not rotatewith the protective shield 104, such as, for example, headgear washer256 or the headgear o-ring 258, may also be referred generally as theconstant-angle portion.

Accordingly, the light source 110 that can be attached to the headgearwasher 256 via the light bracket arm 108 will not move by anysubstantial amount when the protective shield 104, which may be coupledto the rotating coupler 254, is rotated up or down. In variousembodiments, the rotating coupler 254 and/or the protective shield 104may be designed such that the protective shield 104 can stay in anyposition where it is placed. Other embodiments may have detents atspecific positions so that the protective shield 104 can stay at any oneof those locations. The present disclosure is not limited to theprotective shield being in a specific location.

The headband depth positioning slide 252 may also be referred to as ananchor bezel, and the rotating coupler 254 as a bezel rotational lock.

Referring back to FIGS. 1A and 1B, the headgear washer 256 can beconnected to the light bracket arm 108, while some embodiments may havethe headgear washer 256 and the light bracket arm 108 as a single piece.The light bracket arm 108 can be configured to drop down the side of theuser's head with the light source 110 attached to the lower end of thelight bracket arm 108. The light source 110 may be attached to the lightbracket arm 108 by any suitable means. For example, the lower end of thelight bracket arm 108 may comprise a clip that a light source 110 can beinserted in to. For example, the clip may be spread apart when the lightsource 110 is pressed in to it, and then clamp tightly around the lightsource 110 when the light source 110 is in position.

Other types of attachments points could be, for example, ball and socketjoint, magnet, a tube in to which the light source 110 is inserted, etc.The light source 110 may be attached to the light bracket arm 108 suchthat the light source 110 can be rotated to shine the light up or down.When a ball and socket joint is used to attach the light source 110 tothe light bracket arm 108, the light source 110 may be moved side toside as well as up and down. Various embodiments of the disclosure mayalso use another joint to allow side to side movement for the lightsource 110. Accordingly, the light source 110 can be attached to thelight bracket arm 108 via one of many types of light source holders.Furthermore, a flexible bracket can be used for the light bracket arm108 to allow the light bracket arm 108 to be bent to a desired shape toallow the light source 110 to shine to the desired work area.

Accordingly, because the headgear washer 256 locks into the headbanddepth positioning slide 252 that is locked to the support unit 102 sothat the light source 110 stays constantly positioned with respect tothe user's head-worn device 200.

FIG. 3 is a drawing of an example of a light shining on a work areawithout shining into a weld plume, in accordance with an embodiment ofthe disclosure. Referring to FIG. 3, there is shown a welder wearing awelding helmet 300 that comprises the support unit 302 and the weldingshield 304. The light source 310 is connected to the welding helmet 300at the anchor (pivot) point 306 via the light bracket arm 308.

As the welder is welding the work area 313, there may be a weld plume307 that rises from the work area 313. At times, depending on the amountand type of weld plume, light shining on the weld plume may obscure thevision of the welder. Accordingly, it may be desirable at times to avoidshining light on to a weld plume. This is illustrated in this figurewhere the light beam 311 shines on the work area 313 without shining into the weld plume 307. Accordingly, the light beam 311 shines on thework area 313 without being dissipated or obscured by the weld plume307, or illuminating the weld plume 307 to further obstruct vision ofthe welder.

FIG. 4 is a drawing of an example bracket for attaching a light to ahelmet, in accordance with an embodiment of the disclosure. Referring toFIG. 4, there is shown the light bracket arm 408 connected to the anchorbezel 452, with the bezel rotational lock 454 on the underside of theanchor bezel 452. The light bracket arm 408 drops down from the anchorbezel 452 via a bezel rotational lock 454 that is shown in a simplerotational configuration. Other types of pivots could be used at thispoint, such as ball and socket, etc., to give the operator additionalflexibility in positioning the light beam 411. The light source holder410 is coupled to the light bracket arm 408, and securely holds thelight source 410. The light source holder 410 may comprise a lightsource connector 414 for rotatably coupling the light source holder 410to the light bracket arm 408.

For embodiments where the light source holder 410 is directly coupled tothe anchor bezel 452, the light source connector 406 may rotatablycouples the light source holder 410 to the anchor bezel 452.

In various embodiments of the disclosure, the light bracket arm 408drops down from the headgear anchor (pivot) point 106 (or 306) on a sideof a head-worn device, thereby allowing the light source 410 to cast thelight beam 411 on a work area (313) from below the weld plume (307). Thelight bracket arm 408 may also extend at different angles as shown inFIGS. 6A and 6B. Accordingly, various embodiments may have the lightbracket arm 408 set at different angles or have the angle of the lightbracket arm 408 be adjustable and allow it to be locked at differentangles.

Various embodiments of the disclosure also allow the light, for example,the light source 410, to be separated from the light source holder 412to allow the operator to easily remove and replace the light source 410for use in other tasks around the work area. Other tasks could include,for example, inspecting welds or other items needing lighting where ahead-worn device 100 might not allow access. The light source 410 may befurther attached to the light source holder 412 by a retractable cord toallow the light source 410 to be returned more surely. Other embodimentsmay allow the light source holder 412, with the light source 410, to beremoved from the light bracket arm 408. Some of these embodiments mayalso have a retractable cord to allow the light source holder 412 to bere-connected to the light bracket arm 408 more surely.

Various embodiments may configure the light source 410 to connectdirectly, for example, to the light bracket arm 408 with a type ofcorresponding attachment. For example, the light bracket arm 408 couldhave a receiving pin or hole that a corresponding hole or pin of thelight source 410 would snap into, with detents molded into the faces ofthe flashlight or light bracket arm 408 to use for holding the desiredangle of the light source 410.

An advantage of having the light bracket arm 408 directly connected atthe headgear anchor (pivot) point 106 or 306 is that since the lightbracket arm 408 and the light source 410 lowers the center of gravityfor weight borne by the welder, the weight transferred to the user'sneck muscles is reduced.

FIG. 5 is a drawing of an example helmet with an attached light, inaccordance with an embodiment of the disclosure. Referring to FIG. 5,there is shown a grinding helmet 500 with a supporting unit 502, aprotective shield 504, a light bracket arm 508 connected to the grindinghelmet 500 at the anchor (pivot) point 506, and a light source 510.Similarly as described for other embodiments, the light source 510 doesnot substantially move when the protective shield 504 is rotated up ordown.

FIG. 6A is a drawing of an example light attachable to a head-worndevice, in accordance with an embodiment of the disclosure. Referring toFIG. 6A, there is shown a light unit 600 that can be attached to ahead-worn device such as, for example, a welding helmet, a grindinghelmet, etc. Other head-worn devices may be, for example, a fireman'shelmet, a caver's helmet, climbing helmet, bicycle helmet, motorcyclehelmet, safety helmet, etc.

The attachable light unit 600 comprises the light bracket arm 608directly connected to the headgear washer 656, which corresponds to theheadgear washer 256 of FIG. 2. The light source connector 614 fastensthe light bracket arm 608 to the light source holder 612, which holdsthe light source 610.

FIG. 6B is an exploded drawing of an example light attachable to ahead-worn device, in accordance with an embodiment of the disclosure.Referring to FIG. 6B, the exploded view shows the relationships of thevarious parts of the attachable light unit 600.

FIG. 7 is an example flow chart for controlling a light source, inaccordance with an embodiment of the disclosure. Referring to FIG. 7, at700 it is determined whether the light source control is in a manualmode. If it is in a manual mode, then at 702 it is determined whetherthe light switch is in the ON position. If so, the light source 110 isturned on at 704. Otherwise, the light source 110 is turned off (orstays off) at 706. From either 704 or 706, the process may proceed to700.

If it is determined at 700 that the light source control is not inmanual mode, then at 708 it is determined whether the protective shield104 is in a down position. If so, then the light source 110 is turned onat 710. Otherwise the light source 110 is turned off (or stays off) at712. The process may then continue back 700.

Proceeding from 704 or 706 may depend on, for example, an input such asthe light switch and/or the manual/automatic mode being switched.Similarly, proceeding from 710 or 712 to 700 may depend on, for example,detection of movement in the protective shield and/or themanual/automatic mode being switched. Accordingly, it can be seen thatthere are many different ways to control the light, and variousembodiments of the disclosure are not limited to any specific process.

Furthermore, this is just one process for determining whether to turn onor off the light source 110. Other embodiments may determine whether toturn on or off the light source 110 due to one or more light sensorsdetecting ambient light. Still other embodiments may incorporate boththe light sensor and the protective shield position to determine whetherto turn the light source on.

Other embodiments of the disclosure may have a head-worn device with aprotective shield where the light bracket arm is rigidly mounted to theprotective shield so that it moves up as the protective shield isrotated up. However, the light source holder may be configured to swivelto keep the light source shining on substantially the same work area.This may be accomplished, for example, with the light source and/or thelight source holder weighted or balanced properly to maintain thelighting angle when it moves up or down with the rotation of theprotective shield.

Various embodiments have disclosed a protective shield, and there aremany types of protective shields that are encompassed by the disclosure.The present disclosure is not limited to any specific type of shield.For example, many protective shields may be a single piece that coversall or part of a face. Some protective shields, such as, for example,welding shields, may comprise a protective shield that can be rotated upand a visor that can be rotated up independently of the protectiveshield. In such cases of multiple parts that can be rotated up, variousembodiments may generally refer to the protective shield as the largestunit that encompasses the multiple parts. However, the presentdisclosure need not be so limited. For example, for some embodiments,the visor that can be rotated up may also be referred to as a protectiveshield for the purposes of this disclosure.
